Concordia MATH 206 tutoring
Algebra and Functions — one-to-one online tutoring to understand difficult concepts, practise problems and prepare for midterms and finals.
Listed course
Course overview
Concordia MATH 206 reviews algebra and functions through coordinate systems, factoring, graphing, equations and systems, exponents, exponentials, and logarithms. It supports preparation for later quantitative courses.
MATH 206 or equivalent is the listed prerequisite for both MATH 208 and MATH 209. MATH 203 instead requires MATH 201 or equivalent; these routes are not interchangeable.
MATH 206 topics we can help with
Coordinate systems and distanceRadicals and factoringPolynomial graphingRelations and functionsLinear and quadratic systemsExponentials and logarithms
Common difficulties
- Keeping domain restrictions and checking extraneous roots
- Distinguishing roots, intercepts and a quadratic vertex in a model
What this course builds on
Review signed arithmetic and elementary algebra. This course connects algebra to functions and models; its number does not mean it follows Calculus II.
Registration requirements
No formal course prerequisite is listed for MATH 206. MATH 208 and MATH 209 each list MATH 206 or equivalent as their prerequisite.
Check the official course catalogueQuick prerequisite check
Factor x² − 7x + 12 and solve x² − 7x + 12 = 0.
Show the reasoning
(x − 3)(x − 4), so x = 3 or 4. Expand or substitute to check.

How tutoring can help
Pair symbolic exercises with graphical checks. Before manipulating a radical or logarithmic equation, state its domain and test candidates in the original expression.
Exam preparation for MATH 206: midterms and finals
Alternate linear, quadratic and exponential models. Explain why a model fits instead of choosing a formula only because it looks familiar.
